:
Equation at the end of step 1
4ab • (5a2 • b3)
STEP
2
:
Multiplying exponential expressions :
2.1 a1 multiplied by a2 = a(1 + 2) = a3
Multiplying exponential expressions :
2.2 b1 multiplied by b3 = b(1 + 3) = b4
Final result :
(22•5a3b4)
Hey there!
First, we need to find how much Lannie paid for all 12 copies. To do this, all we have to do is multiply the unit price ($19) by how many copies he bought (12)
$19 x 12 = $228
So, he spent $228 on the books, but we also need at add the shipping charge:
$228 + $15 = $243
Therefore, the total cost of Lannie’s order is $243
Hope this helps you!
God bless ❤️

Answer:
Option 4. Perimeter = 30 units
Step-by-step explanation:
Since the volume of a pentagonal prism is 840 cubic units.
Perpendicular distance between the bases = 14 units
We know volume of a pentagonal prism = Area of base × distance between the bases
840 = Area × 14
Area = 840/14 = 60 square units
Now area of a pentagon
Therefore perimeter of the pentagon = 5×a = 5×5.91 = 29.54 ≈ 30 units
